Page 4: Introduction
TI850 blowers are built to exacting standards and if properly installed and maintained will provide many years of reliable service. We urge you to take time to read and follow every step of these instructions when installing and maintaining your Blower. -
Page 5: Installation
INSTALLATION WARNING: Users must provide adequate protection, warning and safety equipment necessary to protect personnel against hazards involved in the installation and operation of this equipment in the system or facility. Do not use air blowers on explosive or hazardous gases. Casing pressure must not exceed 25 PSIG (1.72 bar g). -
Page 6: Lubrication & Oil Capacities
LUBRICATION Every Tuthill blower is factory tested, oil drained and shipped dry to its installation point. Both independent oil reservoirs must be filled to the proper level before operation. Shaft bearings at the gear end of the blower are splash lubricated by one or both gears dipping into an oil reservoir formed in the gear end plate and cover. -
Page 7: Preventative Maintenance
PREVENTATIVE MAINTENANCE A good maintenance program will add years of service to your blower. A newly installed blower should be checked frequently during the first month of operation, especially lubrication. Check oil level in both the drive end and gear end of the blower and add oil as needed. Complete oil changes are recommended every 1000 operating hours, or more frequently depending on the type of oil and oil operating temperature. -
Page 8: Troubleshooting
TROUBLESHOOTING Although Tuthill TI850 blowers are well designed and manufactured, problems may occur due to normal wear and the need for readjustment. The chart below lists symptoms that may occur along with probable causes and remedies. SYMPTOM PROBABLE CAUSE REMEDIES Loss of oil. -
Page 9: Recommended Shutdown Procedure
RECOMMENDED SHUTDOWN PROCEDURE TO MINIMIZE RISK OF FREEZING OR CORROSION When high humidity or moisture is present in an air piping system, condensation of water can occur after the blower is shut down and the blower begins to cool. This creates an environment favorable to corrosion of the iron internal surfaces, or in cold weather, the formation of ice. -
Page 10: Disassembly
DISASSEMBLY Remove all oil drain plug and vent plug from both ends of the blower. Before removing any parts, match mark each component with a punch. This will allow the blower to be reassembled in the same position. Match mark covers, endplates, housing, cover extension, and both rotors. -
